Effective lice control through breeding and genetics

Nr. 1 / August 2016
The battle against salmon lice can only be won by using a combination of preventative and treatment methods. Breeding and genetics is one of the few methods that increase the resistance of fish to lice throughout the whole production cycle. Reduced risk of lice infection, robust fish that tolerate handling and a short production time in the sea are important contributors, the potential of which can be opened up with the use of new breeding technolog

DNA-based tracking for salmon farming

Nr. 1 / May 2014
Escape of farmed salmon is an undesirable event which has negative financial consequences for the farmer, and can lead to genetic impacts on wild salmon stocks. With an increased focus on a sustainable industry throughout the whole value chain, the introduction of a tracking system is a key element of the strategy for documenting the provenance of farmed salmon, and at the same time accountability for salmon producers.

Field documentation of QTL-innOva IPN/PD

Nr. 2 /2013
Pancreas Disease (PD), caused by Salmonid alphavirus (SAV), has for many years been one of the most costly diseases affecting Norwegian salmon farming. Producers and the authorities have implemented a number of structural and operational measures with the aim of limiting losses from this disease. In addition different vaccines against PD have been developed as well as different types of special feed.

Use of QTL-eggs results in an IPN reduction for the whole of Norway

Nr. 1 / 2013
Since the introduction of IPN resistant QTL-eggs in 2009, there has been seen a reduction in the number of recorded IPN diagnoses for salmon by 50 % during the period 2009-2012. Information from both farming companies and national statistics also shows that there has been a considerable reduction in mortality for both 2011 and 2012 generations of salmon in Norwegian fish farming. In the same period the number of QTL-eggs delivered to Norwegian fish farmers has increased greatly. Field investigations to document performance that began at the time of introduction of QTL-eggs underpin our conclusion that both the number and severity of outbreaks has been reduced.

Field results of QTL-innOva IPN – from egg to harvest

Nr.1 / 2012
The first generation of QTL-IPN fish from Aqua Gen has now been followed throughout the entire production cycle. The results show that the prevalence and extent of IPN in both fresh water and sea water were either eliminated or significantly reduced in comparison to previous generations and reference groups that did not possess the QTL-IPN. This positive trend is confirmed by official statistics on the number of registered IPN outbreaks in the Norwegian fish farming industry. It is expected that the increased frequency of IPN resistant QTL fish, combined with reduced infection pressure in the environment will further improve the disease situation and reduce losses in the coming years, resulting in improvements for both animal welfare and profitability in the fish farming sector.

Growth performance of this year’s broodstock – Parents of the forthcoming egg generation 2011/2012

Nr. 1 / 2011
As well as optimal health and robustness attributes, growth is one of the most important criteria for selection of broodstock in Aqua Gen’s breeding program. Broodstock that have been selected to produce eggs for delivery in the forthcoming season 2011/2012 have demonstrated excellent growth performance. By the use of both traditional and QTL-based selection, we will achieve a more precise and predictable transfer of growth and health characteristics of these broodstock parents to their offspring (eggs).

QTL Eggs – Documented IPN Protection from Day One

Nr. 1 / 2010
In the autumn of 2009 Aqua Gen produced for the first time, eggs selected using a gene marker for increased IPN resistance. In the course of the egg season 2009/2010 nearly 50 million of this egg type were delivered to customers. The results of controlled laboratory experiments and feedback from hatcheries show that, to date, the salmon fry produced from these eggs have performed according to expectations and that so far there has been a very high protection against IPN.

World First with Gene Marker Selected Salmon Eggs

Nr. 2 / 2009
New methods in salmon breeding and egg production will be used in this year’s production of Aqua Gen eggs. The world’s first selective breeding company in aquaculture will use so-called gene markers to choose brood fish having offspring with predictably high resistance to the viral disease IPN. This marks a new era in selective breeding work, and will contribute to increased cost-effectiveness and better animal welfare in the fish farming industry.

First Selection for IPN-resistance in Rainbow Trout

Nr. 1 / 2009
Eyed eggs from the Aqua Gen population of Rainbow Trout stripped in 2009 are the first generation with parents selected for increased resistance for IPN. Using selective breeding to reduce the extend of the disease is new within commercial breeding programs.

Good Egg Quality in 2007/2008

Nr. 2 / 2008
During the 2007-2008 season Aqua Gen carried out a programme of exhaustive quality controls at the time of delivery of salmon eggs in Norway. This investigation covered the period from egg delivery to 4 weeks after the beginning of feeding. Generally the results showed a low incidence of non-viable eggs and a high survival rate throughout the whole period. Feedback concerning growth rates after the start of feeding has also been very positive.
